Abstract: An arrangement having a coupling connection comprising two coupling parts. The coupling parts can be connected by means of a screw connection and form a fluid channel. On the first coupling part there is a multi-start thread as a connection means as part of the screw connection. On the second coupling part there is a multi-start mating thread as a connection means as a further part of the screw connection.

Abstract: A filter apparatus consists of a combination of various filter elements combined to form a structural unit, one filter element of these filter elements serving to clean of particles and another filter element to clean oil oxidation products from a fluid stream, the filter elements being mounted in parallel to each other for the respective cleaning of the fluid stream.

Abstract: The invention relates to a filter device, comprising a filter housing (10), which has an inlet (12) for unfiltered medium and an outlet (14) for filtered medium and which accommodates an exchangeable filter element (16). When unfiltered medium flows through said filter element from the outside in, it flows through both a hollow cylindrical element material (18) and an element material (22) which closes the hollow cylinder (18) at one free end (20) of the hollow cylinder. At the other free end (24) of the hollow cylinder, an element cap (26) having a central opening (28) is used to discharge filtered medium to the outlet (14) in the filter housing (10), the outlet being connected to the central opening (28). Each element material (18, 22) is accommodated seal-free in the filter housing (10) for incident flow on all sides, from the outside in.

Abstract: A method of container virtualization in a processor circuit is provided, wherein the processor circuit operates a host operating system and at least one container in which application software is implemented. The processor circuit operates a logging service of the host operating system independently of the at least one container. The at least one container or the application software is coupled by a data channel to the host operating system. The application software outputs at least one message regarding an operation event of the application software in a first format into the data channel. A conversion unit is operated in the host operating system which receives the at least one message from the data channel and converts it from the first format into a host-specific second format, and transfers the converted message to the logging service for logging of the operation event.

Abstract: A method adapts a filter medium to predefinable parameters, such as electrostatic charge, flow-rate behavior, dynamic pressure behavior or differential pressure behavior, fraction filtration efficiency and preservation of a constant quantity and quality of fluid additives. At least one of these parameters is adapted by the targeted influencing of the surface energy of the filter medium (18).

Abstract: The present invention relates to a vacuum safety valve for a vacuum pump, in particular for a rotary vane pump, comprising a housing having a flow path extending between an inlet and an outlet for a gas to be conveyed, a valve region that is disposed in the flow path and in which a valve closure element is arranged that is movable between a closed position and an open position, a control space that is associated with the valve region and in which a membrane separating the pressure side from an operating side is arranged, and a control element active between the membrane and the closure element, wherein the closure element is movable via the control element against a return force from the closed position into the open position by means of the membrane acted on at the pressure side and is movable back into the closed position on a removal of the membrane load due to the return force and is held in the closed position.

Abstract: A filter element (1), with a preferably multilayer structure of a filter medium (3), in pleated form has filter pleats (5, 7) of different pleat heights (h1, h2). The filter pleats (7) with a first pleat height (h1) oppose the filter pleats (5) lower second pleat height (h2). The filter element has a throughflow direction for fluid to be cleaned away from a dirty side to a clean side (R). The transitions arranged adjacent to the inner side all conclude along a fictitious circular cylinder (9), which penetrates the filter medium (3) coaxially to its longitudinal axis (LA).
